Delaware Bay flounder stay hot as NJ season nears its close

What's biting

What's next

With flounder season winding down on the New Jersey side of Delaware Bay, look for effort to concentrate hard on the EP Tower, the lighthouse grounds and the shipping channel edges that Higbee's Bait and Tackle and Big Dave's Tackle have both been keying on. Full moon tides typically mean a stronger push-pull each day, and that extra current should keep bait moving along the channel edges and give bucktail-and-Gulp drifts a better shot at intercepting keeper flounder before the September 25 closure.

Expect the tog bite Big Dave's Tackle is already seeing around jetty rock and bridge structure to keep building over the next few days. Tautog typically respond well to cooling water and the shift toward fall, and green crabs and sand fleas fished tight to structure should keep producing as more fish slide onto the rocks. The oceanfront pickup Hands Too Bait and Tackle described — kingfish and snapper bluefish mixing in with croaker and spot — is a classic late-August signal that bait is starting to stage for its fall move, and that pattern should hold or strengthen into the weekend.

Weakfish action in the 18-to-24-inch range on floated bloodworms along bayshore structure piles is worth watching closely; that's a solid size class, and if the bite holds through the coming days it could turn into one of the more talked-about threads on the bay side heading into September. Anglers targeting sheepshead and tog around the Cape May inlet rockpile and Anglesea rocks should also see steady action continue, particularly on incoming tide stages when current sweeps bait past the structure.

Plan around the full moon's bigger tide swings this week — mornings and evenings around the tide changes should offer the cleanest windows, especially for flounder drifts near the channel and tog fishing on structure. With the NJ-side flounder closure approaching fast, this is the stretch to get out for that species specifically; anglers who want to keep targeting flounder past September 25 will need to shift effort to the Delaware side of the bay, where the four-fish, 17.5-inch limit typically runs through the end of the year. Check current state regulations before harvesting, since exact dates and limits can be adjusted.

Context

Delaware Bay's late-summer pattern this year is running about on schedule. Flounder fishing typically holds strong into the final weeks before the season closes, and Higbee's Bait and Tackle and Big Dave's Tackle both describe a bay-wide bite that's still producing limits and keeper-size fish rather than tailing off early — a good sign for the stretch remaining before the September 25 NJ-side closure. The Fisherman's DE/MD/Chesapeake report frames that closure date plainly against Delaware's later, more liberal four-fish/17.5-inch limit, which is the typical asymmetry between the two states' management of the same bay.

The mix of species showing up — tog and sheepshead moving onto structure, kingfish and croaker holding in the surf and back bays, and a solid class of weakfish on bayshore piles — tracks with a typical late-August-into-September transition for this region, when bottom species pick up as water starts to cool and bait begins staging for its fall migration. Nothing in the current reports points to an unusually early or late shift.

There isn't enough historical comparison data in the available feeds to say definitively whether this year's flounder numbers are running above or below past seasons — the shop reports describe strong fishing in relative terms but don't offer a year-over-year benchmark, so that comparison should be treated as anecdotal rather than confirmed.
